Anatomy and Physiology is a dynamic textbook for the two-semester human anatomy and physiology course for life science and allied health majors. The book is organized by body system and covers standard scope and sequence requirements. Its lucid text, strategically constructed art, career features, and links to external learning tools address the critical teaching and learning challenges in the course. The web-based version of Anatomy and Physiology also features links to surgical videos, histology, and interactive diagrams.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Students are introduced to the circulatory system, the heart, and blood flow in the human body. Through guided pre-reading, during-reading and post-reading activities, students learn about the circulatory system's parts, functions and disorders, as well as engineering medical solutions. By cultivating literacy practices as presented in this lesson, students can improve their scientific and technological literacy.

Following the steps of the engineering design process and acting as biomedical engineers, student teams use everyday materials to design and develop devices and approaches to unclog blood vessels. Through this open-ended design project, they learn about the circulatory system, biomedical engineering, and conditions that lead to heart attacks and strokes.

Eosinophils are a similar size to neutrophils, have a bilobed nucleus and are characterised by the large eosinophilic granules present in their cytoplasm. Produced in the bone marrow they migrate into circulation briefly before moving into tissue where they survive for around six hours. The proportion of eosinophils circulating depends on the state of the animal. Normally numbers are very low but will rise considerably during a parasitic infection or allergic reaction.

Prior to birth the foetus is not capable of respiratory function and thus relies on the maternal circulation to carry out gas, nutrient and waste exchange. The foetal and maternal blood never mix, instead they interface at the placenta. Consequently the liver and the lungs are non-functional, and a series of shunts exist in the foetal circulation so that these organs are almost completely by-passed.

"For people with diabetes, the dangers of high blood sugar are long established. Now, scientists have uncovered additional components in the blood that can worsen the disease. In a new article in the Journal of Physiology, researchers report that microparticles shed from cells under diabetic conditions have unique inflammatory properties that may help explain the multiple organ vascular dysfunction that’s common to the disease. Microparticles have been increasingly recognized as important biomarkers in various health conditions. But most prior reports have relied on in vitro studies to evaluate particle function. Because in vitro experiments can’t fully replicate physiological conditions, defining exactly how microparticles affect disease progression has been tricky. This prompted researchers to look at the link between microparticles and diabetes-induced vascular dysfunction in vivo, in the microvessels of streptozotocin-induced diabetic rats..."

"Heart disease is the leading cause of death worldwide. While people have benefited greatly from advances in drugs and surgery, one glaring problem remains: unlike the cells that make up our other muscles, once heart cells are gone, they simply can’t be regenerated. That is, unless you were just born. Studies show that muscle cells in the hearts of newborn mice, rabbits, and even humans can go on dividing for up to days after birth. And now, in what could be a new world record, scientists have recorded signs of regeneration beyond two weeks after birth in the South American gray short-tailed opossum. Their ability to replicate this feat in mice could point to new ways of healing the hearts of humans with cardiovascular disease. The experiments that led to these results were carried out by Wataru Kimura and colleagues at the RIKEN Center for Biosystems Dynamics Research in Japan..."
